    Abstract:
    A technique for ultrasonically guided percutaneous oocyte aspiration was developed utilizing standard real-time, linear-array ultrasound equipment. Forty-four patients attending our in vitro fertilization and embryo transfer (IVF-ET) program were included in this study. In 38 patients, follicular puncture was performed under general anesthesia and in 6 cases performed under local anesthesia. Fifty-two follicles with a mean diameter greater than or equal to 18 mm were punctured, and 40 mature oocytes were recovered corresponding to a success rate of 77% per follicle. Six of the punctured follicles were considered cystic when the aspirated granulosa cells were examined microscopically and, if these were excluded, the corrected recovery rate was 87% per follicle. In two patients, ovulation had occurred at the time for oocyte collection. In one of these patients, a mature oocyte was, however, recovered from the pouch of Douglas by the use of sonography. On the basis of these results, ultrasonically guided puncture of follicles for collection of human oocytes in our IVF-ET program seems suitable for use in all cases where laparoscopy is presently used and, moreover, in cases with severe adhesions, where laparoscopy may fail.
